Question

In which case would the kinetic energy of particles be increasing? (1 point) Responses Metal is cooled at 1,300°C. Metal is cooled at 1,300°C. Metal is at room temperature, 37°C. Metal is at room temperature, 37°C. Metal is melted at 1,300°C. Metal is melted at 1,300°C. Metal is heated from room temperature to 200°C.

Answer 1

The kinetic energy of particles would be increasing in the case where "Metal is heated from room temperature to 200°C." Heating the metal increases the kinetic energy of its particles as they gain thermal energy and move more vigorously.
